  1. Aa - a r i t h m e t i c , b - g e o m e t r i c , c - W 1 = W 0 e r t , d - L t = L 0 + r t
  2. Ba - a r i t h m e t i c , b - g e o m e t r i c , d - W 1 = W 0 e r t , c - L t = L 0 + r t
  3. Cb - a r i t h m e t i c , a - g e o m e t r i c , c - W 1 = W 0 e r t , d - L 1 = L 0 + r t
  4. Db - a r i t h m e t i c , a - g e o m e t r i c , d - W 1 = W 0 e r t , c - L t = L 0 + r t

Correct answer

D. b - a r i t h m e t i c , a - g e o m e t r i c , d - W 1 = W 0 e r t , c - L t = L 0 + r t

Step-by-step solution

In arithmetic growth, following mitotic cell division, only one daughter cell continues to divide while the other differentiates and matures. Mathematically, it is expressed as L t = L 0 + r t where L t = length at time 't' L 0 = length at time 'zero' and r = growth rate / elongation per unit time. The simplest expression of arithmetic growth is exemplified by a root elongating at a constant rate. In geometrical growth, both the progeny cells following mitotic cell division retain the ability to divide and continue
